XAMPP is a free and open source cross-platform web server solution stack package, consisting mainly of the Apache HTTP Server, MySQL database, and interpreters for scripts written in the PHP and Perl programming languages.

Many people know from their own experience that it's not easy to install an Apache web server and it gets harder if you want to add MySQL, PHP and Perl. XAMPP is an easy to install Apache distribution containing MySQL, PHP and Perl. XAMPP is really very easy to install and to use - just download, extract and start.

To install XAMPP you only need to download and extract XAMPP, that's all. There are no changes to the Windows registry (not true if you use the Windows installer version of XAMPP) and it's not necessary to edit any configuration files. It couldn't be easier!
